WEATHER-STRIP.

Patented March 1 6, 1 909;

Application filed May 18, 1908. Serial No. 433,460.

' being had therein to the accompanying drawings, forming part thereof.

My invention relates to weather-strips and is particularly adapted for application to the meeting rails or check rails of window sashes.

The objects of my invention are simplicity and inexpensiveness of construction, durability, prevention of rattling, and a high degree of efficiency in excluding wind, rain and dust.

Other objects and advantages will appear from the following description. 7

My invention includes two coacting strips so shaped and related the one to theother ancl to the sash rails as to produce a double sea My invention more particularly includes a tongue extending into a groove and an. overlapping ledge or lip closing the mouth of the groove.

My invention also includes a tongue extending at an angle from the strip on one sash rail and adapted to enter a groove inclined at an opposite angle'and formed by the other strip on the other sash rail.

My invention also includes otheradvantageous features and several details of construction, as will hereinafter appear.

I will now describe my invention with reference to the accompanying drawingsand will thereafter point out my invention in. claims. Figure 1 is a vertical section through the meeting rails of the upper and lower windowsashes and through the two parts of the weather-strip. Fig. 2 is a vertical section of the upper rail or meeting rail of the lower sash and the portion of the weather-strip carried by it. Fig.3 is a side elevation of the same. Fig. 4 1s a vertical section of the lower rail or meeting rail of the top sash and the portion of the strip carried by it. Fig. 5 is a side elevation of the same.

In the embodiment of my invention illustrated in the drawings an up. er rail or meet; ing rail 1 of a lower sash am a lower rail or meeting {rail 2 of an upper sash are shown as provided with coacting inclined meeting. faces.

My invention includes complementary members or strips 3 and 4 secured respectively to the upper rail or meetin rail 1 of the lower sash and to the lower rai or meeting rail 2 of the upper sash. The members or strips 3 and 4 are constructed of sheet metal bent to the required form or shape, sheet zinc being well adapted to the purpose.

The member or strip 3' is bent back double upon itself and has its mutually adjacent edge portions bent to form a flange 11' which seats in a slot in the sash rail 1 as shown.- The outer doubled portion of the member 3 lies flat against the meeting face of the rail 1 which is rabbeted as shown to receive the member 3 so as to provide an even or flush surface, and the member 3 is secured to this rabbeted surface of the meeting face of the sash rail 1 by nails or the like, as shown' in Fig. 3. The sash rail 1 is also provided with rabb ets at 5 and at 6 (see articularly Fig. 2), and the folded edge of the strip or member 3 )rojects beyond the edge of the rabbet 5 an parallel with the inclined meeting face of therail 1.

The strip or member 4 has a flange 7 seated in a's'lot in the meeting face of the lower rail ormeeting rail 2 ofthe top sash, and has a flat portion lyin'g against such meeting face, the meeting face being rabbeted to provide an even surface as shown in the drawings.

.T hefmember 4is secured to this rabbeted nails or the like as mav be seen in Fig. 5. he member 4 is bent or folded upon itself to form a sealing tongue 8, which extends u wardly at an oblique acute angle to the inc med meeting face of the rail 2, and themember or strip 4 is further bent and folded to form a ledge or lip 9, substantially of double thickness, which extends horizontall at an angle to the tongue 8 shown as slightly less than a right angle, and a )ortion 10 0f the member 4 extends below anr lies in contact with the outer exposed face of thesurface b rail 2 and may be secured to the rail by nails or the like.

In, operation when the sashes are closed together, as shown in Fig. 1, the ton ue 8 enters the groove formed by the mem er 3 and the rabbet 5-, and, because of the opposite inclinations or opposite angular positions .ofthe walls of this slot and of the tongue 8,

forms therewith a groove which is and also by reason of the fact that when the meeting'rails 1 and 2 are brought together by vertica movement in closing the window such movement is in a plane oblique to the surfaces of the rabbet 5 and of the tongue 8,

the folded edge of the member 3 will ress against the tongue 8 at one side-thereo and near its base and the face of the rabbet 5 will press against the other side of the tongue 8 adjacent to its free edge, thereby securing a tight seal of the tongue in the groove. Also when the sashes are in closed position the lip 9 overlaps the edge of the rail 1 and fits against the faceof the rabbet 6, closing the space betweenthe rails 1 and 2 and closing the mouth of the groove formed by the rabbet 5 and the member 3. Thus the tongue 8 and the lip 9, to ether with the other coacting parts as above described, provide a double seal between the meeting rails 1 and 2 and effectively exclude wind, rain and dust. Also rattling of the sashes is prevented because of the fact that they are firmly held together by the coacting weather strip members.

It is obvious that various modifications may be made in the construction shown and above particularly described within the principle and scope of my invention.

I claim:

1. A weather-tight. joint comprising, in combination with two relatively movable parts, two members, one upon each part, one member at the meeting face of one of the parts and forming a groove therewith, and the other member at the meeting face of the other (part and provided with a tongue ada te to engage in the groove formed by t e first member and to be pressed in the groove to form a. seal and also provided with alilp extending away from the part u on .whic the member is carried and exten ing across the mouth of the groove so as to close the mouth of the contact with the other art.

2. A weather-tight oint, comprising, 'in combination with the meeting rails of a window, one of the rails having a rabbet formed in its meeting face, a member secu'redfiat against the meeting face of the rabbeted rail and projecting beyond theed e of the rabbet thereof to form'a groove t erewith, and a second member attached to the meeting face of the other rail and provided with a tongue ada ted to engage in the groove formed by t. e first member and to be pressed re e y in the groove to form a seal and also provided with a lip extending at an angle to the tongue and rmmg a projecting ledge adapted tooverlap' the edge of the first meeting rail and close the mouth 'of the groove to form a second seal.

' 3. A weather-tight joint comprising, in

combination with tworelatively movable arts, one of the parts having a rabbet ormed in its meeting face, a member secured flat against the meeting face of the rabbeted part and projecting beyond the edge of the rabbet to form therewith -a groove, and a second member secured to the meeting face of'the other part and provided with a tongue extending from the meeting'face and adapted to engage in the groove formed by the-first member, the opposite faces of the groove lying at oblique angles to corresponding sides of the tongue, whereby pressure is brought to bear on o posite sides of the tongue by the face of t e rabbet at one side and by the first member at the other side and a tight seal thereby secured.

4. A weather-tight joint comprising, in combination with two relatively movable arts, one of the parts having a rabbet ormed in its meeting face, a member secured fiat against the meeting face of the rabbeted 'part and projecting beyond the edge of the rabbet to form therewith a groove, and a second member secured to the meeting face of the other art and provided with a tongue extending om the meeting face at an oblique angle and adapted to engage at an oblique angle in the groove formed by the first member, the second member being also provided with a li extending at an angle to the tongue and a apted to overlap the edge of the first member and close the mouth of the groove.

5. A weather-tight joint com rising, in

combination with the meeting ra i s of a window, one of the rails having a rabbet formed in its meeting face, a sheet-metal member secured flat against the meeting face ofthe rabbeted rail and roj ecting beyond the edge -01: the rabbet to orm a roove therewith, a second sheet-metal mem er secured to the meeting face of the other rail and bent to form a tongue extending obliquely to the meeting face and ada ted to engage obliquely in the groove ormed by the first member, so that the first member presses on one side of the ton ue and the face of the rabbet presses on t e other side of the tongue, the second member being also bent to .form an extended lip adapted to overlap the edgeof the first meeting rail and close the mouth of the groove, the second member also having a portion overla ping the edge of the second meeting rail an secured to the free exposed face thereof, substantially as se't'fort t In testimony whereof I have affixed my signature in presence of two witnesses.
